论文摘要
我们探讨了一种影响甚至控制两极分化社会群体中观点多样性的方法。我们利用选民模型，在该模型中，用户持有二进制意见，并根据与之联系的其他人反复更新他们的信念。从未改变思想（“狂热者”）的顽固代理也通过网络传播，网络以连接的图为模型。在早期结果的基础上，我们为该组平衡的平均意见提供了封闭形式的表达。这使我们制定了一种策略，将狂热者注入两极分化的网络，以将平均意见转移到任何目标价值上。我们说明了可能存在适中效应的情况，这可能导致该组做出负面反应并加强其在响应中的极化水平。我们的结果得到了合成数据的数值实验的支持。
We explore a method to influence or even control the diversity of opinions within a polarised social group. We leverage the voter model in which users hold binary opinions and repeatedly update their beliefs based on others they connect with. Stubborn agents who never change their minds ("zealots") are also disseminated through the network, which is modelled by a connected graph. Building on earlier results, we provide a closed-form expression for the average opinion of the group at equilibrium. This leads us to a strategy to inject zealots into a polarised network in order to shift the average opinion towards any target value. We account for the possible presence of a backfire effect, which may lead the group to react negatively and reinforce its level of polarisation in response. Our results are supported by numerical experiments on synthetic data.
